C: Natural Resources FOLDER: Nature Preserve Master Plan FILE: Zone Definitions - Revised PRC Endorsed 4/8/03 NATURE PRESERVE Definition: High quality natural areas that preserve the biodiversity of the region by contributing to the long-term viability of plant and animal populations, natural communities and/or entire ecosystems. Acquisition or designation of sites of any size is authorized where warranted to protect a significant ecological, geological, or archaeological resource. Objectives: Nature preserves, as designated by the Mecklenburg Board of County Commissioners, are declared to be at their highest and best use for public benefit by serving one or more of the following public purposes: (1) Contribute to the growth and development of public understanding of and empathy for natural systems, and the consequent development of public understanding for the interdependence of all forms of life and vital dependence of the health of the human community on the health of other natural communities. (2) Provide sites for scientific research and examples for scientific comparison with more disturbed sites. (3) Provide sites for educational activities and places where people may observe natural biotic resources and environmental systems. (4) Provide habitat for the survival of rare plants or animals or natural communities or other significant biological features. (5) Provide opportunities for contemplation or outdoor recreation compatible with the protection of the natural area. (6) Provide places for the preservation of natural beauty or unique or unusual natural features. (7) Provide large, contiguous undeveloped natural lands in perpetuity for the purpose of conserving open space and creating wildlife corridors within densely developing urban areas. (8) Provide small habitat areas within development that can act as "stepping stones" to habitat corridors or between larger protected habitat areas. (9) Designation of 1,000 acres each shall be the minimum goal for Latta Plantation, McDowell and Reedy Creek Nature Preserves. NATURAL ZONE Definition: Areas exhibiting significant biological diversity and ecological processes. Hierarchy Level: 1 Management Priority: Conservation and restoration of natural communities and the protection of plant and animal species. Protected Natural Area Definition: Natural heritage sites (as documented in the Mecklenburg County Natural Heritage Inventory) and other fragile areas whose natural features and/or ecological processes are subject to serious impairment if opened to the public. Hierarchy Level: 1A Management Priorities: (#1) Site monitoring, scientific study and management to preserve and/or restore the area's ecological integrity and natural heritage values. Improvements: Improvements must be compatible with the preservation, interpretation and management of ecological features and natural resources. No new trails shall be permitted. Existing pedestrian trails (natural surface only). Existing equestrian trails (natural surface or stone surface). Service roads (natural surface or stone surface) for management purposes. Improvements shall be restricted to the smallest area necessary to accommodate required development and use and to minimize environmental impacts. Public Access: Restricted. Limited to guided tours by DNR staff, except where trails accessible to the public currently exist, and to scientific researchers working under special permit issued by DNR. 2 Outstanding Natural Area Definition: Areas exhibiting a significant diversity of flora, fauna, natural communities, rare species, geologic features and/or archaeological resources. This designation shall also include shoreline buffers (minimum 100 feet wide) along the Catawba River and regulated floodplains along tributary streams. Hierarchy Level: 1B Management Priorities: (#1) Site monitoring, scientific study and management to preserve and/or restore the area's biological diversity. (#2) Provide public access that will not adversely affect the integrity of the natural features and ecological processes. Improvements: Improvements must be compatible with the preservation, interpretation and management of ecological features and natural resources. Pedestrian trails (natural surface, stone surface or approved stream/wetland crossings) and interpretive signage for educational and passive recreational purposes. Existing equestrian trails (natural surface or stone surface). Service roads (natural surface or stone surface) for management purposes. Improvements shall be restricted to the smallest area necessary to accommodate required development and use and to minimize environmental impacts. Public Access: Restricted to trails. Natural Area Definition: Areas that provide general plant and wildlife habitat and buffer sites of higher ecological significance from adjacent land uses. 3 Hierarchy Level: 1C Management Priority: (#1) Site monitoring, scientific study and management to conserve and/or restore the area's natural resources. (#2) Provide public access that will not adversely affect the integrity of the natural features and ecological processes. (#3) Provide facilities for environmental education. Improvements: Improvements must be compatible with the preservation, interpretation and management of ecological features and natural resources. Non-motorized, multi-use trails (any surface material) and interpretive signage for educational and passive recreational purposes. Motorized wheelchairs are permitted on trails. Service roads (any surface material) for management purposes. Nature centers, observation decks/towers and supporting infrastructure compatible with the interpretation of natural resources and ecological processes. Improvements shall be restricted to the smallest area necessary to accommodate required development and use and to minimize environmental impacts. Public Access: Not restricted. CULTURAL AND HISTORICAL ZONE Definition: Areas to be managed for the preservation, protection and interpretation of cultural and historical resources. Cultural and historical resources include properties listed or eligible for listing in the National Register of Historic Places, along with resources not eligible for the register, but worth preserving for interpretive or other management purposes. 4 Hierarchy Level: 2 Management Priority: (#1) Protection of cultural and historical resources for public visitation and education. Improvements: Improvements must be compatible with the preservation, interpretation and management of cultural/historical values and resources. Educational centers and associated infrastructure. Facility restorations. Non-motorized, multi-use trails (any surface material) and interpretive signage for educational and passive recreational purposes. Motorized wheelchairs are permitted on trails. Service roads (any surface material) for management purposes. Improvements shall be restricted to the smallest area necessary to accommodate required development and use and to minimize environmental impacts. Public Access: Limited to public areas, trails and cultural/historical structures. SUPPORT DEVELOPMENT ZONE Definition: Areas where facility development and intensive use may substantially alter the natural environment. Hierarchy Level: 3 Management Priority: (#1) Facility maintenance and management. Improvements: Improvements must support visitor use or nature preserve management. Typical improvements include: paved roadways, parking lots, maintenance facilities, operational support buildings, primitive camping areas*, boat access, fishing piers, restroom facilities, utility easements. 5 Improvements shall be restricted to the smallest area necessary to accommodate required development and use and to minimize environmental impacts. * Existing campground at McDowell Nature Preserve will be allowed to remain as part of this zone, however, any future campground development shall be of a primitive design (no hook-ups or drive-to sites). Public Access: Limited to public areas. 6
